52c on new CPU

post #1 of 12
Thread Starter 
Hiya,

I just changed out a 3700 sandy with an X2 3800 along with a case change. First run I hit 52 load with stock settings (MB temp 35c). Took off the heat sink and used the one from my sandy (It ran around 42c while folding) and used AS5. Wow, it dropped 3 whole degrees!

This case has front, rear, side and top fans. I took the side cover off and put a floor fan blowing into it and the temp went up, so looks like case fans are doing the job.

Is it common for the temp settle down because of the new install? Thought I read that can happen?

Other than the temps, everything else is fine. What do you think?

Too much TI perhaps? Those temps to seem awfully high! I would try re-applying your TI, and maybe investing in some AS5. Also, what HSF are you using? It is common for temps to lower over time, but I do not think you will see more then a 3c drop in most cases.

It takes a while, like 200 hours for the as5 to "settle". But 52°C does seem to high, are you sure you applied as5 right and seated the heatsink properly?

Reseat your HS and give your CPU time to burn in. Burn-In time is a myth, but meh. What stepping did you get?

I used AS5 on the stock HS. My AM2 3800 is running at 42c folding on both cores with the stock HS. This one is at 49c right now folding on both cores.

Is there a trick to putting on AS5 and setting the heatsink? It all went together without any problems. Reseat it? Won't that make it worse?

The steping is identical to viscountvics: http://www.overclock.net/1263510-post1.html

What I do, and find most effective, is put a pea sized amount of AS5 on the CPU, and spread it as finely as possible covering the whole surface area (to spread it I use a credit card). Other people just put a pea sized amount of AS5 on the CPU, slap on the HSF, and rotate it afew times. I have done both, and found the first method kept temps lower. If you reseat you will have to re-apply the AS5, make sure you clean off both the HSF and the CPU real well before reseating.

Thanks,

I'll give that a try in the morning, I'm pretty beat right now. I'll let it fold overnight, it's holding at 49c.

OK, I used your prefered method and dropped 2 more degrees, 47c now. I will just have to wait to see if it settles in. I don't even want to try any hard core games right now, worried it will get too hot. I shouldn't have to spend more money on another heat sink to run at stock temps!

I have to say, the credit card trick worked great! I used plastic wrap before but the card made it spread thin and flat. Looked even better than the factory job and definately better material. Rep worthy, thanks.

A BB size is all you need, if you put too much then it will act as a barrier instead of letting the heatsink absorb the heat. As5 is to fill in the imperfections of the surfaces. Get a better heat sink then you shouldn't have any overheating problems. I have a X2-3800 @ 2.8ghz full load is only 46c. thats with a typhoon.

Your temps are fine. Heat doesn't do damage until around 75*C... at the lowest.
